Title: Procede de recuperation d'une proteine soluble
Inventor: SHIMAMOTO NOBUO
IPC: C07K1/14
Filed: 1999-05-17
Abstract: On décrit un procédé qui permet de récupérer une protéine soluble avec un rendement de récupération élevé. Le procédé consiste à inhiber l'agrégation de la protéine au moment d'éliminer un agent dénaturant d'un liquide solubilisé contenant la protéine solubilisée. L'invention concerne également un procédé qui permet d'inhiber l'agrégation de la protéine en éliminant l'agent dénaturant du liquide solubilisé, comme indiqué plus haut. Ce procédé de récupération consiste à solubiliser un agrégat de protéine insoluble à l'aide d'un agent dénaturant, puis à éliminer l'agent dénaturant du liquide solubilisé afin de récupérer la protéine soluble. Le procédé se caractérise en ce que l'élimination de l'agent dénaturant s'effectue en présence de 60 à 99 % par volume d'un polyol (alcool dihydrique à tétrahydrique), suivie de la dilution du liquide ainsi traité à l'aide d'un diluant. Ce procédé d'élimination consiste à éliminer l'agent dénaturant du liquide solubilisé après solubilisation de l'agrégat de protéine insoluble, ladite élimination s'effectuant en présence d'un polyol (alcool dihydrique à tétrahydrique).

IPC: F24H3/06
Filed: 2001-06-18
Abstract: An electric space heater uses the heat generated by quartz-halogen lamps to heat air which may be supplied to heat a local space. The heater conducts air through a heater enclosure in which the lamps are installed. The air path is parallel to the longitudinal axis of the lamps. The air is warmed by conduction from the surface of the lamps and from heated walls surrounding the lamps and which form the air flow path.     The walls are heated by radiation from the lamps. The flow path for the heated air and the placement of the heated walls substantially isolate the outer portion of the heater enclosure from the heat generated by the lamps to maintain the temperature of the outer surface of the space heater at or near ambient temperature. The walls also confine the light generated by the lamps to the interior of the space heater. The air flow through the space heater is assisted by an electric fan.
